So here's what I remember: Somebody, somewhere, had come up with an interesting idea on how to graph the "shape" of requests coming in to an HTTP server.
They did it like this: They analyzed the graph, taking note of things like timestamps, unique IPs, pages accessed, etc. What they did from there was graph these unique elements on vertical line, such that earlier entries would be towards the top, later entries towards the bottom, and each vertical line represented one of the above data elements (first vertical line is timestamp, second vertical line is vhost, third vertical line is path, etc.).
The interesting thing they did was draw lines between each of the unique elements. For a given entry in a log file, a line would be start from the point on the vertical "timestamp" line at 3pm, then be drawn to the corresponding location on the "unique IP" vertical line, and then to the "virtual host" vertical line.
After drawing a couple thousand of log entries, one could get an idea what the "shape" of one's log traffic looked like (is it all coming from one IP? all hitting the same address? all at the same time?), and could easily identify patterns, etc.
I'm not necessarily looking for an implementation, just that if somebody else has seen this, and remembers the name for this, or who did it, I'd be interested to know it for further research.
